15. 15 Other CPUC DG Programs  Self Generation Incentive Program  Net energy metering (NEM)  Feed-in-Tariffs

16. 16 Self Generation Incentive Program (SGIP)  SGIP was the largest DG incentive program in the country (prior to CSI)  Represents over $1 billion in total project costs  As of March 31, 2008, approximately 1200 operating facilities (~300 MW of capacity installed)  Program was initiated by AB 970 (Ducheny, 2000)  Started in response to California peak demand problems  Developed to pursue load control and distributed generation  Annual Budget  $83 million/year

17. 17 SGIP Technologies & Incentives Incentive Level $/watt Eligible Technology 20072008** Solar PV* * Wind turbines$1.50 Biogas fuel cell$4.50 Natural gas fuel cell$2.50 Biogas microturbines (MT)$1.30 Biogas internal-combustion engines (ICE)$1.00 Large biogas turbines$1.00 Natural gas microturbines$0.80 Natural gas internal-combustion engines$0.60 Small natural gas turbines$0.80 Large natural gas turbines$0.60 *Solar PV technologies were removed from SGIP effective 1/1/2007 **AB 2778 limits SGIP to wind and fuel cells effective 1/1/2008  Eligible technologies have included both renewable and fossil fuel powered systems  Incentives have been capped at 1MW  Maximum system capacity = 5MW Renewable fuel Nonrenewable fuel

18. 18 Net Energy Metering (NEM)  Net Energy Metering:  Customers may offset utility charges with credits from onsite power production.  Systems up to 1 MW are eligible.  NEM customers are exempt from standby charges and interconnection fees.  NEM Eligible Technologies:  Solar photovoltaics and wind turbines receive credit based on the full retail rate.  Biogas-fired generators and fuel cells receive credits at generation portion of the rate.

19. 19 Feed-in-Tariffs (FiT)  What is a feed-in-tariff?  Standard offer contract for the sale of energy from a qualifying DG facility to the utility grid  CA experience with FiT - Qualifying Facilities (QFs)  Public Utilities Regulatory Policy Act (PURPA) of 1978 established QFs and outlined their payment according to the avoided cost of power  QF is defined as non-utility generator with less than 80 MW capacity that utilizes cogeneration and/or renewable fuels (for bioenergy, ≥ 50% biomass)  New CA feed-in-tariffs  AB 1969 (Yee) – Renewable FiT  AB 1613 (Blakeslee) – CHP FiT

20. 20 AB 1969 (Yee) Renewable Feed-in-Tariff  Tariffs for the purchase of eligible renewable generation up 1.5 MW  Statewide cap of 478.4 MW  Fixed price is determined by the Commission, adjusted for time of delivery and season  Contract periods of 10, 15 and 20 years  Tariffs transfer Renewable Energy Certificates (RECs) from generator to utility  Two options under tariff (depending on customer’s choice):  Full sale of production  Excess sales (after onsite usage)

21. 21 AB 1613 (Blakeslee) CHP Feed-in-Tariff  Feed-in-tariff for Combined Heat and Power DG  Fixed or variable price to be determined by the CPUC  Eligibility:  CHP up to 20MW  CHP systems must be sized to meet customer’s thermal load. There is no requirement that CHP systems be sized to the customer’s electric load. Thus, oversized systems (from an electric perspective) are permitted.  Only new CHP systems (installed after January 1, 2008) are eligible.  NOX emissions limit of 0.07 pounds per MWh
